FIELD OF THE INVENTION

The present disclosure relates to a medical device, and, more particularly, to a surgical instrument.

BACKGROUND OF THE INVENTION

A variety of complete surgical procedures and portions of surgical procedures may be performed with bipolar forceps, e.g., bipolar forceps are commonly used in dermatological, gynecological, cardiac, plastic, ocular, spinal, maxillofacial, orthopedic, urological, and general surgical procedures. Bipolar forceps are also used in neurosurgical procedures; however, the use of bipolar forceps in neurosurgical procedures presents unique risks to patients if the surgeon is unable to both visually and tactilely confirm that an electrosurgical procedure is being performed as intended. Accordingly, there is a need for a bipolar forceps that allows a surgeon to both visually and tactilely confirm that an electrosurgical procedure is being performed as intended.

BRIEF SUMMARY OF THE INVENTION

The present disclosure presents a bipolar forceps. Illustratively, a bipolar forceps may comprise a first forceps arm having a first forceps arm aperture, a first forceps jaw, and a first forceps arm conductor tip; a second forceps arm having a first forceps arm aperture, a second forceps jaw, and a second forceps arm conductor tip; and an input conductor isolation mechanism having a first forceps arm housing and a second forceps arm housing. In one or more embodiments, the first forceps arm may be disposed in the first forceps arm housing and the second forceps arm may be disposed in the second forceps arm housing. Illustratively, an application of a force to a lateral portion of the forceps arms may be configured to close the forceps jaws. In one or more embodiments, a reduction of a force applied to a lateral portion of the forceps arms may be configured to open the forceps jaws.
